1' 0 all whom it may concern:

Be it known that I, RICHARD H. lVIATHER, a citizen of the United States,residing at Windsor, (post-office address Hartford ,)in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in the Process of Winding the Ring- Magnets of DynamoElectric Machines, of which the following is a specification.

My invention relates to an improved, process of winding the ring-magnetof dynamoelectric machines; and the objects of my invention are to windthe ring-magnet more expeditiousl y than formerly, and. in such mannerthat the wire upon the spool or between the magnet-ring and the spoolwill not kink or twist up into knots in the process of winding.

The accompanying drawing represents one of my magnet-rings in theprocess of being wound and the manner of winding the same.

I first make a hole in the upper part of the ring-magnet A and thread itproperly to receive the threaded, end of the rod 13. This rod isprovided with a head, a, at its ,upper end, and it is passed through thebracket or plate I), which is secured to the ceiling of the room inwhich the process is to be carried on. The rod passes loosely throughthe plate I), so that it is free to turn therein after the manner Of aswivel. This rod is screwed into the hole in the upper part of thering-magnet, so as to suspend the ring a convenient distance above thefloor, and so that itis free to be revolved, as shown in the drawing.After suspending the ring-magnet in this manner the wire is woundthereon from a suitable spool or bobbin by turning the ring-magnet uponthe swivel-joint with one hand, while the operator merely guides thewire by the other hand and passes it through the opening at the bottomof the ring at each revolution thereof. In this manner of winding, thewire comes di rectly up from the spool without any twists or anytendency to become entangled, and the ring can be wound much moreconveniently than it would be possible to do were the magnet held in astationary position.

I claim as my invention- The herein-described process of winding aring-magnet, which consists in suspending the same so as to be readilyrevolved, then revolving the ring, while the wire, whose end is securedthereto, is guided and passed through the opening at the bottom of thering for every revolution thereof, substantially as described, and forthe purpose specified.

RICHARD H. MATHER.
